"For this, he realized, was the future. It was a place without a single feature of the space-time matrix that he knew. It was a place where nothing yet had happened—an utter emptiness. There was neither light nor dark; there was nothing here but emptiness. There had never been anything in this place, nor was anything ever intended to occupy this place—until this very moment when he and his machine had been thrust upon it, intruders who had overstepped their time."

“To cover up actual lack of knowledge, the tale develops an explanation which amounts to divine intervention. It is an easy and, to the primitive mind, a plausible and satisfactory way to explain something of which nothing at all is known.”

“The party was beginning to get noisy—not boisterous, but noisy. It was beginning to acquire that stale air of futility to which, in the end, all parties must fall victim.”

“Without consciousness and intelligence, the universe would lack meaning.”

“My reluctance to use alien invasion is due to the feeling that we are not likely to be invaded and taken over. It would seem to me that by the time a race has achieved deep space capability it would have matured to a point where it would have no thought of dominating another intelligent species. Further than this, there should be no economic necessity of its doing so. By the time it was able to go into deep space, it must have arrived at an energy source which would not be based on planetary natural resources.”

“It was not his fight. Not personally his fight. No more his fight than any one of them. But he had made it his. Because of Stone, because of Rand and Harriet, because of priest who’d hounded him across half the continent, he had tried to make a fight of it. And perhaps, as well, because of something undefinable, unknown to himself, unsuspected in himself—some crazy idealism, some deep-rooted sense of justice, some basic aversion to bullies and bigots and reformers.”

“It would be three-dimensional chess with a million billion squares and a million pieces, and with the rules changing ever move.”
